Natural Drainage Systems (NDS) Designs
30% Design Phase
This project consists of designing and constructing a natural drainage system at four locations in Northeast Seattle. The project goals are to improve Thornton Creek water quality and decrease the chance of flooding downstream.
The South Thornton Natural Drainage System (NDS) Project has completed the 30% Design Phase. At the 30% Design Phase, we present potential street and drainage improvements to the community, answer questions, and gather community concerns as we work toward finalizing project scope based on regulatory requirements and project funding.
